This study presents a cost-effective 3D printing technique for manufacturing large-area tubular PCFCs, allowing for low-cost material preparation and achieving exemplary shape/dimension-controlled uniform microstructures. The 3D-printed tubular PCFC exhibits a high power output and long-term stability, indicating its potential for realistic applications and scale-up.
Protonic ceramic fuel cells (PCFCs) are clean and efficientpowergeneration devices operating at intermediate temperatures. However,manufacturing difficulties have limited their commercialization, especiallyfor promising tubular PCFCs. Herein, we report a cost-effective 3Dprinting technique for manufacturing large-area tubular PCFCs (e.g.,15.7 cm(2)), featured with the use of commercial raw materials,a small amount of binder, and a CO2 laser for rapid insitu drying. The technical advantages enable low-cost material preparationand efficient achievement of exemplary shape/dimension-controlleduniform microstructures in porous anode support, dense electrolyte,and porous cathode. The 3D-printed tubular PCFC (& SIM;12.5 cm(2)) exhibits a power output of 2.45 W at 650 & DEG;C. Meanwhile,the long-term stability is confirmed during 200 h of operation. Thisnovel 3D printing offers great potential to advance PCFCs from thelaboratory to larger scales for realistic applications.
